- Keep doing story missions until you finish the mission at the Space Needle. When you finish that mission it unlocks the ability to do the graffiti collectibles which you need to 100% the different areas.
- The Paper Trail thing is not worth doing. They shut down all the online stuff so there's no context or variety for what you're doing which is pretty much padding the runtime with yet another chase and taking pictures from really far away because Delsin doesn't know how zoom works. If you DO decide to slog through it when you finally get to what it calls part 4 just head to that place with the giant fish sign in Market District. Originally you had to find a picture online so you knew to go there but that's what happens when you stupidly tie things to websites.
